FIELD OF THE DISCLOSURE

The present disclosure is generally related to orthodontic treatment facilities, and more particularly to a mobile orthodontic treatment system and method.

BACKGROUND OF THE DISCLOSURE

Orthodontic services are traditionally performed within a dental or orthodontic facility. Large equipment, such as dental panoramic radiography equipment, otherwise known as panoramic machines, require relatively large spaces to operate. A panoramic machine is a two-dimensional (2-D) dental X-ray examination that captures the entire mouth in a single image, including the teeth, upper and lower jaws, surrounding structures and tissues. Other equipment, such as digital scanners, are also required in the orthodontic facility.

Orthodontic services require a patient to visit the orthodontic facility for periodic treatment. Patients often take time from work or school to visit the orthodontic facility. There is a need for a mobile orthodontic treatment facility that can transported to the patient. For example, rather than the patient visiting the facility, the mobile system can be brought to the patient, whether it be a school or a place of work.

Additional hardware including cabinets for storage is also provided. The mobile orthodontic treatment facility may also include supply carts capable of being secured for storing and moving around supplies.

The trailer can further include a dental chair, which is sometimes referred to as a dental engine. The dental chair is a large chair-side appliance that is typically used in a dental office. The dental chair includes a source of mechanical and/or pneumatic power to one or more handpieces used by the orthodontist. The dental chair can also be configured to include a small faucet and a spit-sink to rinse the patient's mouth. Suction hoses and a water nozzle can be provided to clean the patient's mouth. Other devices supported by the dental chair can include an ultrasonic cleaning appliance, a small table to hold an instrument tray, a work light, and a computer monitor or display.

As mentioned, the trailer is configured to be pulled by a vehicle, such as a pickup truck having a trailer hitch. However, the chassis of the trailer can be configured to be pulled by any type of trailer configuration. Moreover, as mentioned above, the trailer can be embodied in a recreational vehicle.

A method of treating a patient requiring orthodontic services is also disclosed herein. For a new patient, the orthodontist would typically recognize the various characteristics of a malocclusion or dentofacial deformity, define the problem, design a treatment strategy based on the problem, and provide a treatment strategy. Depending on the problem or problems, it is possible that there may be more than one course of treatment for the patient. A typical treatment plan can include removing teeth for overcrowded mouths and applying an apparatus for moving the patient's teeth. When using an apparatus, such as braces (visible or invisible), a treatment plan can take one to two years to complete, with the apparatus being altered, albeit slightly, every four to six weeks. Thus, a patient over the course of a two-year period can expect to visit the orthodontist up to fifteen visits.

One advantage associated with trailer 10 is that the trailer can be moved to a place convenient to the patient. For example, the trailer can be brought to the patient's work or school location. The trailer can thus services many patients located in a common location. In one embodiment, a patient enters the trailer through the main door or through the primary or main entrance or through the secondary entrance if disabled. The patient's records can be stored in the one or more cabinets provided in the trailer or stored electronically on the computer. For a new patient, as described above, to evaluate the patient, the orthodontist would most likely obtain a panoramic X-ray and a digital scan of the patient's teeth. Thus, the patient would obtain the panoramic X-ray at the panoramic machine and a scan at the digital scanner. The digital scanner would have to be extended to us deployed or use position. The patient's mouth can be examined in the dental chair.

For a return patient, an updated panoramic X-ray and an updated digital scan of the patent can be obtained by the panoramic machine and the digital scanner, respectively. Based on the results, the orthodontist can alter the apparatus to progress the patient's treatment. This process continues until the patient's treatment is completed.

The mobile orthodontic treatment facility of embodiments of the present disclosure has several advantages. The mobile orthodontic treatment facility is easily transported over the roadways without requiring any extensive transportation means. The mobile orthodontic treatment facility is capable of being completely self-sufficient and may include generator power, running portable water, biohazardous waste disposal, lighting, heating, air conditioning and air filtration.

Having thus described several aspects of at least one embodiment of this invention, it is to be appreciated various alterations, modifications, and improvements will readily occur to those skilled in the art.
